Abstract
A method and an apparatus for determining an encryption key associated with an integrated circuit having a memory plane that includes a matrix of electric contacts on it's surface and a layer of inhomogeneous electric resistivity material disposed on the matrix. An encryption key is determined by the integrated circuit on the basis of the random distribution of the electrical resistances connecting the various electric contacts of the matrix.
